Thank you SideFX for the great work! I hold a deep respect for the amazing amount and quality of development (and support! <3), which you are able to deliver! I am so much looking forward for the presentations and another mind blowing world of possibilities with H20.

Following on the discussion: Please, what is the development status of MaterialX in Blender? Or status/roadmap of export of USD with MaterialX? When can we expect to be able to import it "flawlesly" into Houdini?
I have found this:
https://projects.blender.org/blender/blender/issues/112864 [projects.blender.org]
But I don't have an overview of the situation and possible involved complications.

Can we expect a new VEX "context", running per Frames (similar to Points) and per Channels (similar to Primitives) in SOPs? I know there is CHOP vex context, but a rewrite would be amazing. I am using "proxy" geometry for such operations (and it is reliable, useful, but cumbersome).

I am curious, why this works for the flipsolver:
But for the pyrosolver it doesn't:
Although the initial folder names are the same (defined by the type properties).
Both solvers are the SOP level HDAs:
hou.node('/obj/geo1/flipsolver1').parm("folder11").set(4)
But for the pyrosolver it doesn't:
hou.node('/obj/geo1/pyrosolver1').parm("folder11").set(5)

I have also noticed in the documentation, that the proper place to set the HQROOT override is not in houdini.env, but here:
C:\HQueueClient\hqnode.ini (under the job_environment section)

If I understand it right, there is a way to submit from a local folder (without UNC)
- set the Network Folder Variable Name HQROOT to Windows Mount H:
- save the file in the H:\folder\file.hiplc
- submit the job
- on the server, H: is replaced with $HQROOT
- on the client, have the $HQROOT set in the houdini.env like this:
HQROOT = //192.168.1.200/h
- so... on the client, HQROOT points at the network drive
Everything seems to work, is it common to have such overrides?
Local access to a drive (without UNC, when developing the file) can be much faster.

Please, can we work directly in the H:\folder\ and have the submitter submit the //192.168.1.200/H/folder/ path?
The submitter seems to do some automatic "replacement" between these locations:
- file locations, if being placed in the Mount location H: (or //192.168.1.200/H/)
- environment variable HQROOT
Can it convert on the server (or the client) from H: into //192.168.1.200/H/ ?
I am on Windows 11.

Hello, I am also curious about the NDI output from Houdini. Are there any news in developing/utilizing this interface?
Houdini Engine for Unreal » Houdini rotation to UE4 rotation?
- ikoon

Thank you very much @dpernuit
I wanted to match the rotation of Houdini camera (exported from Houdini to USD and imported with USD Stage Unreal plugin). I managed to get it working, but I had to shuffle the quaternion different way.
I inverted y coordinate in quaternion instead of w:
hou.Quaternion(x, z, -y, w)
In UE, there should be left handed coordinate system, but rotating around X and Y axes in UE follows the right hand rule. Can someone please shed some light on this?
(btw I also had to pre-rotate the Houdini camera with hou.hmath.buildRotateAboutAxis(world_cam_UP_vector, 90) so that it looks the same direction as UE cam)

Hello Bryan, thank you so much for explanation! I did not even know about such use of Context Option, neat!

Please, from a "one man, one .hiplc" perspective, what would be an ideal way to toggle Sopimport's Load from disk versus import "live" from sops?
The attached solution, is it a right way to do the toggle?
Also, can the Sopimport`s Layer Save Path be written to disk without downstream USD ROP?

Thank you very much for your answer! My mistake, I have insufficient understanding of USD and Solaris.
I was worried about some obvious (not so obvious to my limited knowledge) "cooking issue" or creating circular dependencies, when previewing many GEOs in /obj (with all the extracted sopnets) and trying to render all of them in /stage at the same time.

Thank you very much Yunus! I should check the changelog next time.
Unfortunately updating to .416 did not help, but maybe it is related. I will report it.

Hello, as in the attached gif. (I have set Blue color as an active window)
I am on Windows 11. I don't remember this happening before. What might be wrong, please?

Solaris and Karma » Custom Sopmodify, using obj/geo instead of inner Subnet

I don't work in any pipeline, I do motion graphics, and I like many aspects of Solaris
I have a plan to create custom Sopmodify HDA, which will dive into "its" obj/geo.
My plan is to:
- import USD assets made in other software, into Solaris
- modify and animate those imported assets in /obj/geo (instead of the inner subnet)
- create another effects in another obj/geo nodes (and sopimport them into Solaris)
- preview all the objects and animations in the /obj context
- do the lighting and rendering in Solaris
Please, is there any technical problem about it?
I realize this is not how USD and Solaris was meant to be used.
But for my "one man, mainly SOPs and DOPs and fast viewport preview of animations", this feels like a way to go.

Thank you! I am sorry I was unclear. I wanted to say that I have to find another way to organize and filter my (quite simple, freelancer's) scenes. I still have some idea of "folders" or "tags". Those primitive patterns should help. USD feels like learning Houdini once again but I like it, thank you for the great work on Solaris!

Excuse me for hijacking the thread, but in case of Solaris being the rendering stage of a project, shouldn't we completely avoid /obj/geo and do the /stage/sopcreate for all the geo instead?

Thank you very much for clarification! I believe this lack of wildcards in Fetch LOP is on purpose.
